Grade 3: Measurement and Data

Solve problems involving measurement and estimation of intervals of time, liquid volumes, and masses of objects.

NY-3.MD.1

Fully covered
Tell and write time to the nearest minute and measure time intervals in minutes. Solve one-step word problems involving addition and subtraction of time intervals in minutes.
(Content unavailable)

NY-3.MD.2a

Mostly covered
Measure and estimate liquid volumes and masses of objects using grams (g), kilograms (kg), and liters (l).
(Content unavailable)

NY-3.MD.2b

Fully covered
Add, subtract, multiply, or divide to solve one-step word problems involving masses or liquid volumes that are given in the same units.
(Content unavailable)

Represent and interpret data.

NY-3.MD.3

Fully covered
Draw a scaled picture graph and a scaled bar graph to represent a data set with several categories. Solve one- and two-step “how many more” and “how many less” problems using information presented in a scaled picture graph or a scaled bar graph.

NY-3.MD.4

Fully covered
Generate measurement data by measuring lengths using rulers marked with halves and fourths of an inch. Show the data by making a line plot where the horizontal scale is marked off in appropriate units—whole numbers, halves, or quarters.
(Content unavailable)

Geometric measurement: understand concepts of area and relate area to multiplication and to addition.

NY-3.MD.5

Recognize area as an attribute of plane figures and understand concepts of area measurement.

NY-3.MD.5.a

Fully covered
Recognize a square with side length 1 unit, called “a unit square,” is said to have “one square unit” of area, and can be used to measure area.

NY-3.MD.5.b

Fully covered
Recognize a plane figure which can be covered without gaps or overlaps by n unit squares is said to have an area of n square units.

NY-3.MD.6

Fully covered
Measure areas by counting unit squares.

NY-3.MD.7

Relate area to the operations of multiplication and addition.

NY-3.MD.7.a

Fully covered
Find the area of a rectangle with whole-number side lengths by tiling it, and show that the area is the same as would be found by multiplying the side lengths.

NY-3.MD.7.b

Fully covered
Multiply side lengths to find areas of rectangles with whole-number side lengths in the context of solving real world and mathematical problems, and represent whole-number products as rectangular areas in mathematical reasoning.

NY-3.MD.7.c

Fully covered
Use tiling to show in a concrete case that the area of a rectangle with whole-number side length a and side length b + c is the sum of a × b and a × c. Use area models to represent the distributive property in mathematical reasoning.

NY-3.MD.7.d

Fully covered
Recognize area as additive. Find areas of figures composed of non-overlapping rectangles, and apply this technique to solve real world problems.
(Content unavailable)

Geometric measurement: recognize perimeter as an attribute of plane figures and distinguish between linear and area measures.

NY-3.MD.8a

Mostly covered
Solve real world and mathematical problems involving perimeters of polygons, including finding the perimeter given the side lengths or finding one unknown side length given the perimeter and other side lengths.

NY-3.MD.8b

Fully covered
Identify rectangles with the same perimeter and different areas or with the same area and different perimeters.
